Not so much as pranks...but stuff that happened at regionals/nationals in prior years.
I believe it was my first year when one of the guys SCALED THE HOTEL! Uhg..what are they called...they've got the three hooks and you can hang from rooftops with them. Well whatever they were, he had one...and...well...made use of it
The same year, we badly trashed our hotel room. We stacked everything in the corner of the room. Then me and one of my roomies pressed down on the mattress on the very top while the third guy hoisted the TV into the small space left

Maids, have fun!
Lesser things are microwaving everything in site. Soap, towels...whatever.
We had icefights outside the AllStar resorts. Ice + cement = immense slippage
In regionals, I think someone duct-taped a bible to the outside of their window.
Uhh...the windows didn't open all the way when we checked in. They did when we checked out
Stuff was duct taped. `nuff said.
That's all I can really remember.
Oh yeah...I ended up with a whole bunch of towels/napkins and other stuff from the hotel at regionals.
